## About Senlo

Senlo is a layer on top of the email delivery provider a team already uses, such as Resend, Postmark or any SMTP server. It gives you a visual editor for transactional email templates, with rows, columns, merge tags and conditions, and versions you can roll back to. Templates can be sent through a single API request, and developers receive the same template through the API without writing MJML by hand.

Lifecycle automations start from events sent to the API, such as a new contact being added. An automation can send an email, wait, check your own API whether a user did something, and then take a different path. Each node shows how many contacts are in it. Sends, deliveries, bounces and engagement are shown per workspace, with a live feed of failures and a suppression list. Senlo renders, personalises, tracks and decides, then hands each message to the provider you chose, so switching providers does not require editing templates.

The product suits teams that send transactional email and onboarding sequences and want editors who do not write code to work on them. It can be self-hosted with Docker Compose under the AGPL-3.0 license, or used as a hosted service with a free plan for one person, and paid plans that add members, roles and audit logs.

## About Zuzu Club

Zuzu Club is a free, anonymous space for peer support and emotional expression. It has no signup, no login and no account. Visitors can choose one of three ways to feel lighter: privately release a worry in Let Go, where it drifts into the night sky; share a feeling anonymously in the Sky of Thoughts and see what others feel; or chat one to one by text with a real stranger in Vent and Listen. Chats with a person are not saved or read.

The site works in any browser and is open around the clock to people around the world. A clearly labeled AI Companion is offered only when no one is available to chat. Zuzu is recommended for people 16 and above, or younger with the awareness and guidance of a parent or guardian.

Zuzu is aimed at people carrying something they cannot easily say to the people in their own lives. It is peer support and self-expression, not therapy, counseling or a crisis service. The site directs people in crisis to a free helpline.
